The hair transplantation process
Separating the hair follicles
The average number of hairs on a human head is between 90,000 and 140,000. This means about there are about 120-200 hairs per cm2. The average density around the nape of the neck is roughly 260 hairs/cm2. The DHT-insensitive hair follicles found just above the nape of the neck are the most valuable hair transplant subjects: these hairs are thick and strong, and retain their hormone insensitivity even after being transplanted.
This is the region of the head from where we select the donor hairs, the size and shape of which we design to fit the individual. The skin in this area responds extremely well to local anaesthetics so general anaesthesia is unnecessary. The first step in the hair transplant process is to select grafts, using a thin and sharp circular knife blade sometimes called a punch tool that produces cylindrical grafts. Each graft is no larger than 1 mm in diameter and encompasses just one natural group of hair follicles, called a follicular unit that contains 1 to 4 hairs.
Preparing the grafts for transplant
The grafts are harvested from their original location and prepared under a microscope for the implant. The treatment cleans and streamlines the grafts.
We count the number of hair follicles each graft contains throughout the process. Our surgical assistant sorts the grafts by the number of hair follicles in each, and then moves them to a four-slot Petri dish separating the grafts by the number of follicles they contain (1, 2, 3 or 4). When the Petri dish is full, the assistant simply counts the numbers of grafts of each type. This gives us the exact number of hairs that are ready for implanting.
Implanting the grafts
The graft implant process is also performed using local anaesthesia. Based on the outcome our patient would like and our own experience, our transplant professionals design the best possible arrangement of the follicular units, including the orientation, angles and density of the future hairs on each part of the recipient site. Then, using an implanter, we transplant the grafts into the chosen areas.
Results and recovery
Speedy recovery, high success rate
Since our micro-puncher harvesting technology enables us to remove separate follicular units with minimum injury, the puncture wounds on the donor site heal extremely rapidly. No inpatient care is required after the intervention. Some of our patients go to work the next day.
Since the hair follicles are protected by the cylindrical tissue surrounding them the risk of damaging them during the implantation process is very low. With this transplant method, 97% of the hair follicles will produce hair growth in the recipient region.
The new hair will be strong and fully equivalent to the rest of your hair. No special treatment is needed in day-to-day care or when getting a haircut.
